    摘要: A process for forming a pattern on the interior side of a face plate of a color picture tube by using a photosensitive composition comprising p-diazo-N,N-dimethylaniline chloride-zinc chloride double salt and a p-diazo-bromophenol chloride-zinc chloride double salt and conducting imagewise exposure of coated film of the photosensitive composition to light and contacting with powder particles at least one time gives higher sensitivity compared with a conventional process.

    摘要: A method of forming a color picture tube fluorescent screen by so-called dry process. After a photosticky substance mainly containing a diazonium compound is coated on a panel inner face, phosphor is adhered to portions of the compound which have been exposed to light through a color selection electrode and rendered sticky, and surplus phosphor applied on unexposed portions of the compound is removed, the above steps being consecutively repeated for phosphors of three colors to form picture elements of triads of three color phosphors on the panel inner face. The panel inner face is then treated with an aqueous solution containing at least polymer coagulant.

    摘要: A photosensitive composition becoming sticky upon exposure to light which comprises (a) a salt of a diazonium compound represented by the formula ##STR1## wherein R.sub.1 and R.sub.2 are independently --H, --CH.sub.3, --OCH.sub.3 or ##STR2## but R.sub.1 and R.sub.2 cannot be ##STR3## at the same time; and R.sub.3 and R.sub.4 are independently a straight-chain lower alkyl group, and (b) a salt of an aromatic diazonium compound having no --OH group directly bonding to a benzene ring, has an improved sensitivity because it contains the salt of the compound represented by the above formula. By using said photosensitive composition, there is provided a process for forming a pattern of powder coated layer excellent in light sensitivity.
